Hi there.

195.249.122.1 =3D FreeBSD 2.2.6
195.249.122.2 =3D Win98
195.184.60.2 =3D DNS=20

Why is it that when I set "ipfw add deny all from 195.249.122.2 to =
195.249.122.1" I'm still able to ppp to 195.249.122.1 from to the =
computer I just denied?? If I ping 195.249.122.1 from 195.249.122.2 it =
says "request timed out" as it should, but when I do anything that has =
something to do with ppp the modem just dials as usual & everything =
"works". Why is that? Isn't "deny all" suposed to filter out all packets =
from 195.249.122.2 letting nothing through?
- thanx up ahead!
